India's food minister on Wednesday ordered safety checks on Nestlé India's Maggi instant noodles after regional food inspectors said the test batches of the popular snack were found to contain dangerous levels of lead.
The Swiss-based food giant has challenged the findings since the results of a first test in Uttar Pradesh hit the headlines.

But the city government of India's capital on Wednesday slapped a 15-day ban on Maggi noodles and said it would launch a criminal case against Nestlé India on allegations of food adulteration.
Prime Minister Narendra Modi's national government followed up by ordering an investigation of a product that accounts for 15-20 percent of Nestlé's revenues in India.
"We are not going to wait for all the reports to come," Food and Consumer Affairs Minister Ram Vilas Paswan told reporters.
"The reports that are coming out - whether they are right or wrong, that I do not know. But the issue is serious."
'Seven times the legal limit of lead'
The Food Safety and Drug Administration in Uttar Pradesh found lead content of 17.2 parts per million (ppm) in routine tests on Nestlé instant noodles - seven times the legal limit.
In response Nestlé India said that it had conducted internal and external tests of 125 million Maggi packets which showed "lead levels are well within the limits specified by food regulations and that Maggi noodles are safe to eat".
Nestlé's troubles have been aggravated by a separate incident in the southern state of Tamil Nadu where one consumer filed a complaint after he allegedly found insect larvae in Nestlé's NAN PRO-3 baby formula.
The company said on Tuesday it had not been contacted by the consumer or the authorities in relation to this matter.
Future Group, one of India's biggest retailers, has taken Maggi noodles off its store shelves, but the product continues to be widely available at corner shops, food stands and cafes.
Sanket Chheda, owner of Bites restaurant in Mumbai, India's financial capital, said he had seen a small dip in demand for Maggi noodles that he serves cooked.
"The dip in demand in very marginal. I'm waiting for a definitive verdict on this. Till then, I'm not thinking of taking it off the menu," he said.
Nestlé could not immediately be reached for comment, but said earlier it had not yet heard officially from the authorities, besides an order from Uttar Pradesh to recall Maggi products.

Meanwhile, South African consumers can continue enjoying Maggi Noodles, Nestlé SA's Media Relations Manager Millicent Molete told Health24.
"We would like to reassure our South African consumers that the quality and safety of all our products are non-negotiable priorities for us, and our Maggi Noodles are therefore absolutely safe for consumption.
She told Health24 that Nestlé SA does not use the same recipe for its Maggi Noodles as Nestlé India.
"We do not use the same recipe. Nestlé is a decentralised company and our products are manufactured locally at our Maggi factory in Babelegi, Tshwane," Molete said.
